Title: Metallurgic converter for puddling pig - iron
IPC: C21C5/48
Filed: 1970-07-07
Abstract: Oxygen-enriched oxidation gas and endothermic gas are blown separately through nozzles in the converter floor from a main pipeline system which ends below the converter near the blast box. The lower section of the converter is formed by two separate supply systems which are a continuation of the main system. One of these comprises the blast box which directly supplies the pipeline leading to one of the nozzles. The other consists of a detachable frame with fixed pipelines which are firmly connected to the tube of the other nozzle. The latter tube passes through the box between the box cover and the fixed pipelines. All supply lines have similar minimum lengths so that each gas is fed into the converter under identical conditions.

Patent FR-2155886-A1 (FR)
Title: Laminated plastic construction panels - covering a reinforced plastic frame work
IPC: B29C70/00
Filed: 1971-10-13
Abstract: Laminated surface sheets are formed by applying a first layer of synthetic material about 0.4-0.6mm. thick to a heated, polished metal surface, causing it to partially gel, applying a second coating of longitudinally prestretched fibres impregnated with synthetic material, bonding the two layers together by applying impacts perpendicular to the surfaces, polymerising the assembly and cooling the metal surface to release the laminate. Construction panels are formed by inserting regularly repeating filling elements between the two surface sheets and bonding them to the sheets by immersing their extremities in the incompletely polymerised synthetic material. The thickness of the second layer is pref. a multiple of that of the first layer, which is pref. covered with a synthetic protective film. A metal foil may be used to prevent transmission of vapour through the fibrous layer. The filling elements may be elastomeric and cellular. Opt. concrete may be used to fill the spaces between the elements and the surface sheets. The panels can be readily fabricated continuously and have better mech. props. than previous panels.

The soln. opt. contains H3PO4 and pref. compsn. is 6-14 esp. 10 vol. 50% diluted commercial HF, 24-36 esp. 30 vol distilled water, >60 esp. 70 g HF4F per 100 cm3 of Hf water-H3PO4 (if any) and if present 1-10 (4-8) esp. 3 vol. conc. H3PO4. The Si nitride to be etched layer may be on III-V type semiconductor, e.g. (GA+Al) arsenide. Method avoids supplementary treatments between deposit of Si nitride and deposit of lacquer or between the lacquer etching and the nitride etching and avoids use of hot conc. H3PO4 which also attacks the substrate.

Title: Folding tip up seat with controlled return - uses gas spring with hydraulic damping fitted to seat and pivot for shockless action
IPC: A47C7/56
Filed: 1974-02-01

Title: Sepn. of particles, esp. fibres, from gas stream - using cyclone with perforated wall to prevent agglomeration of fibres
IPC: B01D45/12
Filed: 1974-05-03
Abstract: A sepg. process and separator for removing solid particles from a stream of gas which is directed as a downward vortex against the inner face of a cyclone shell, the shell being perforated so that the force of the vortex is lost progressively by leakage through the perforations, thus gradually freeing the suspended particles from centrifugal support so that they fall to the bottom of the cyclone. The perforated shell is pref. housed inside a coaxial casing to provided an empty jacket space in which a second vortex operates in the outer face of the cyclone shell, creating a back press. on the perforations; the second vortex is conveniently formed of purified gas escaping through the perforations of the cyclone shell. Sepn. of suspended, solid particles from a gas, partic. sepg. fibres from an air current. The recovery of fibres for re-use is facilitated because fibres do not agglomerate in this separator, i.e. they do not ball up and roll on the inner face of the cyclone because of the progressive loss of vortex press. since the fibres do not become tangled, they fall separately to the cyclone outlet and this allows this type of separator to be incorporated in a continuous process line using individual fibres.

Title: Double grooved carrying pulley for ski lift - retains cable if derailed and still gives free passage to supports
IPC: B61B12/02
Filed: 1974-07-05
Abstract: The carrying pulley (2) is on a horizontal shaft on a pole (5). It has two grooves (6) (7), one supporting the cable (8) and the other catching the cable if derailed from the first. The outside (6a) of one groove (6) is of less diameter than the inside (6b) to allow free passage of attachments (9a) of the support (9). The other groove (7), being a derailment safeguard, is much deeper. There is a fixed slide way (11) with its end specially positioned and with an upper branch (11b) and lower one (11c) carried on a fixed support (12) and another (13). This gives a derailment safeguard, without affecting the passing of supports.

Title: Rotary machine working as pump or motor - has semicircular plates linked at spherical joint to disc in spherical casing
IPC: F01C3/06
Filed: 1974-09-24
Abstract: The machine has a spherical casing assembled from two hemispherical components. Inside the casing is a first semicircular plate (5) which is wedge shaped and can rotate about an axis in its own plane and perpendicular to its diametral edge. It is linked by means of a spherical support bearing (9) to a second similar plate (6) which can also rotate about an axis in its own plane and perpendicular to its diametral edge. A disc (15) is linked to both semicircular plates at the spherical support. The plates and disc separate the inside of the sphere into four spaces and when the two semicircular plates rotate, they impart a combined rotating and oscillating movement to the disc which varies the volumes of the spaces.
